1F TOYOTA LAND CRUISER ENGINE BLOCK, CYLINDER HEAD & INTAKE MANIFOLD
We are stoked to heard that some of you are converting your 1958 – 1974 1F powered Toyota FJ40 Land Cruiser to electronic fuel injection now that we have our 1F Sniper Modification accessories. But one such occasion, the customers had made his parts purchase only to find out that what he really had under the hood of his new to him FJ40, was an 2F engine.
We recently ran into a situation where an 40-Series owner had an 1F intake manifold mounted onto a 2F engine! So, we wish to help you spot the key elements that will quickly tell you if in fact that your Land Cruiser is equipped with a 1F Toyota Land Cruiser engine.
For this particular 1F engine setup we are showing you around what is technically an F.5 or “F-and-a-half” which came in 1973 – 1974 model FJ40 Land Cruisers. So lets start at the top with the intake manifold.
1F INTAKE MANIFOLD
Five elements will signal that you have a 1F intake manifold:
• 3 Mounting Bosses; Oil Filter Housing
• 2 Bung Casting; blank bung & Port for Manifold Vacuum
CYLINDER HEAD
This cylinder head number is 60051 from an F.5 (F-and-a-half) engine from 1973 to 1974, but based on the number chart below one might consider this head a pre-1969 head? Maybe what we are seeing is Toyota used one set of part numbers for the factory parts and another set of numbers for replacement parts. We are not sure!

ENGINE BLOCK
On the driver side of the 1F engine blocks (F120, F130, F145, F155), you will see the extruded provision for the External Oil Pressure Regulator.
This particular F-Series engine block is the F.5 / F.1/2 as Toyota transitioned to an internal Oil Pressure Regulator, thus sealing up the through-hole and bolt intrusions.
ENGINE MOUNTS
F-Series Engines use 10mm X .125 engine mount bolts. 2F engines are 12mm X .125
SERIAL NUMBER
F-Series Engine block serial numbers typically start at “5XXXXX”
